Stratiomyidae? Xylophagidae? A very elegant and sizable fly. Did not get any response for this on the Japanese diptera forum.

It has the feel of Rhagionidae. If you can get Nagatomi to have a look at it...

The wing venation indeed looks like those of other Rhagionidae species.

But the jizz of this fly was drasticly different. Also this is a giant species compaeref with others.
But I observed only Chrysospilus and Rhagio spp. so far, at least as far as my identified Rhagionidae are concerned. But there are around 5-6 more smaller genera around in Honshu.

Is Nagatomi still alive? There are descriptions from him from the early 50s, so he must be well into his late seventies at least.

I know there were a number of papers a few years back and I have not heard that he died.

Could this be Coenomyiidae? I have never seen a fly of this family (in a collection or live). They should be rhagionid-like but larger on average (around 2 cm for many genera). Illustrations in Vol 2 of the Key to the insects of Russian Far East show similar general habitus and wing & thorax pattern. But similar characters are also found in other related families (Athericidae, Xylomyidae in addition to those mentioned above).
Nagatomi & Saigusa have published a paper on Japanese Coenomyiidae in 1970 (Mem. Fac. Agr. Kagashima Univ. Vol 7:257-292). Perhaps you could find this paper?
No, I don't read Russian:(, I have the Keys for the illustrations alone. This is very unfortunate since much of the literature for our nice taiga/tundra zone flies is in Russian.
